I want to set height of my scrollableDataTable in percents like height="100%", and I expect table to be expanded to bottom end of my jsp, but it does not happen. For now I can set height only in pixels. Would you help me please?

One more question. Is there any way to set one row selection only on scrollableDataTable?

1) height="100%" is not a table specific problem at all. Try to work with simple div with such size. I think you wanted the table to fit you browser size - but it will fit body size(or direct parent if present) instead.2) https://jira.jboss.org/jira/browse/RF-2282
